Always found this to be one of the MG Duels' coolest features: Bandai actually engineered a cool cockpit block for it! The Duel's cockpit bay is shown open like...once in the show. It's understandable why they didn't do it sooner; the Duel has a pretty "unique" abdominal structure that doesn't look made to accomodate a cockpit hatch. Bandai was awesome enough to actually make it work though; props to them!
